Sites that require more than four simultaneous users must add a Metasys Server. If a large number of graphics are required to navigate through a site, the addition of the Metasys Server allows access to a disk drive or network drive for graphic file storage. The Metasys Server provides permanent storage of collected trend data samples, event messages, and audit trail messages routed from the network engines.
